yum install java doesn't work.  You have to go to the site and download the rpm.....
I haven't done it yet, but I plan to.
 
 
 
Yesterday I had my server "heavy" day.  Things worked at normal speeds.  I am not sure what happened last week.  However the server was extremely slow.  I used the System Monitor and watched it all day. 
 
Yesterday, when things were slow it was either:  a lot of network usage or CPU usage, but not both.
 
In the morning the students were on Window boxes using Flash and Samba.  I think some of them were working directly off of the server:  saving/executing.  I think that might have slowed things down.  I asked them to copy the file onto their desktops and work from there and then save it to their folders.  It seemed to work a bit better.
 
During the afternoon (they were on a Linux box), there was no noticable lag.  I also asked the students to try to use Opera instead of Firefox.  They complained a bit but it was nice to see the CPU numbers go down.
 
I'm hoping that it'll stay this way for at least the rest of the week.  =]
 
Thanks for all your help!
